Identity and locality
Lasiancistrus schomburgkii (Günther, 1864)
Amazon, Orinoco and Essequibo drainage groups, South America
Diagnostic evidence and naming
2005 systematic revision treats earlier Lasiancistrus pictus, castelnaui, caquetae, guapore, multispinis and scolymus as synonyms, not separately valid species; high variability in abdominal plating and fin spots. The Catalog of Fishes traces the original 1864 Chaetostomus name and subsequent Lasiancistrus combination, which is a taxonomy event rather than an ornamental breeder cross.
Breeding and genetics limitations
Do not count historical six names as six strains or imply all river populations share a tested captive genotype.
